Discovery of Radioactivity - Chemistry LibreTexts
Jan 30, 2023What They Had Discovered: We now have the essentials to utilize radioactive elements. Roentgen gave us x-rays, Becquerel discovered radioactivity, the Curies were able to discover which elements were radioactive, and Rutherford brought about transmutation and the "splitting of the atom." All of these discoveries and curiosity came with a price.
